1301mm BLow-orr ATTACHMENT.

Application filed an 23,

To all whom it may concern;

Be it known that W6,BURT Y oAKUMand WILLIAM E. New, citizens of the ,United States, residing, respectively, in Kansas City, in the county of Wyandotte and State of Kansas, and at Kansas Cit in the county of Jackson and State of issouri, have invented a certain new and useful Improvement in Boiler Blow-Off Attachments, of which the following is a'specification.

Our invention relates to improvements in boiler blow-oil attachments. It is particularly well adapted for use in connection with locomotive boilers.

The object of our invention is to provide an attachment which is simple, cheap to make, durable, not liable to get out of order, which will very much reduce the noise produced in blowing off a boiler through the blow-01f cock, which will eliminate liability of injury to persons and to propert in the vicinity, which can readily be'attac ed to a locomotive boiler, and which is eflicient in operation.

The novel features of our invention are hereinafter fully described and claimed.

In the accompanying drawing, which illustrates the preferred embodiment of our invention,

Fig.1 is a side elevation of our im roved blow-off attachment, shown mounte on a locomotive.

Fig. 2 is an enlarged longitudinal vertical sectional view on the. line 22 of Fig. 3, of

our improved attachment.

Fig. 3 is an end elevation of the same.

Fi 4 is a cross section on the line H ofFig. 2, partly broken away. I

Similar reference characters designate similar parts in the different views.

The attachment comprises an expansion receptacle which may consist of two heads 1 and 2, connected with each other by a horizontal longitudinal outer cylindrical shell 3, having on its under side one or more openings comprising an outlet communicating with the atmosphere.

The head 1 is provided with a central threaded hole which forms a steam inlet for the receptacle and-in which is fitted one end of a conducting ipe 5,, the other end of which is connected to the discharge portion of a blow-off cock 6, of a locomotive boiler 7.

Intermediate of the steam inlet and the outlet opening 4 is provided battling means 1921. Serial I'm-171,811.

shell 3. The shells 8, 9, 10 and 3 may have their ends respectively located in concentric grooves 11, provided on the inner side of each head 1 and 2.

Longitudinal bolts 12 extend through the heads 1 and 2, between the shells 10 and 3,

and have mounted on their respective ends nuts 13 which bear against the outer sides of the adjacent heads.

The conductor 5 discharges into the inner shell 8. The latter is provided with a plurality of longitudinal rows of openings 14, which discharge into the shell 9. The latter is provided with longitudinal rows of openings'15, which discharge into the shell 10.

The latter is provided with longitudinal rows of openings 16, which discharge into the shell 3.

The holes 14, as shown in Fig. 4, are located out of alinement with the holes 15 and the latter are located out of alinement with the holes 16, the latter being disposed out of transverse alinement with the outlet openings 4. By means of this arrangement, an eflicient battling means is afforded.

The head 2 is provided with a central screw-threaded hole extending therethrough which is normally closed by a removable screw plug 17 which upon removal permits access to the inner shell 8, for the purpose of cleaning the latter. a 00 Attached at its ends to the periphery of the shell 3, is a longitudinal arcuate plate comprising a deflector 18, which is spaced apart from and extends across the outlet openings 4. 1

The deflector 18 has open discharge ends, across which respectively extend curved inclined deflectors 19 and 20, which are respectively secured at their upper ends to the heads 1 and 2, and which are sfpaced apart from the adjacent ends of the de actor 18. The deflector 19 inclines forwardly and downwardly and the deflector 20 inclines rearwardly and downwardly. whereby steam discharged from the ends of the deflector 18 1 will be deflected downwardly at an angle against theground.

Thc receptacle is supported by means of two vertical bars 21 and 22, which are respectively secured to the heads 1 and 2, and

' ment and steam will be lown through the conductor 5, into the shell 8, and thence through the openingsl into the shell 9. and through the opening into the shell 10,

' passing from thence through the openings 16, into the outer shell 3, and from thence through the o ening 4, against the deflector 18,"from whic they will e discharged firom both ends of the deflector 18, against the defiectors 19 and 20, which will deflect them obliquely downwardly against the ground.

The force of the discharge will be greatly reduced when the discharge is directed against the ground, so that no damage will be done to the right of way or the road bed, and the direction of the discharge is such that persons or cars which are at the side of the locomotive adjacent to the attachment will not be injured by the discharged material. By disposing the rece web, as shown in Fig. 1, so that the disc arge is longitudinally with respect to the locomotive, the liability ofinjury to a bystander or to adjacent property is eliminated.

The receptacle is made of suflicientsize to permit of great expansion of the "steam. whereby it is discharged therefrom at a very low pressure and with little noise.

=We do, not limit our invention to the" structure shown and described, as manymodifications, within the scope of the appended claims, may be made without departing from the spirit of our invention.

,What we claim is 1; The combination with a blow-off cock of a locomotive boiler, of a horizontal receptacle carried by the locomotive and having an inlet and provided with a bottom outlet communicating with the atmosphere, a deflector spaced apart from and extending across said outlet, and a conductor connecting said inlet with said cock, substantially as set forth.
